vApplicationlinea ivray e,

To allai/'710m t may concern Be it known that l, GEORGEV WILLIAM Ti-roiias, a subject of the {King of GreatV Britain, residing at Williamstown Beach.,4

Victoria, Australia, have inventedcertain new anduseful Improvements inShip Con! structions.; and l do hereby declare the iol# lowing to be a ull, clear, and exactdescrip tion i of the. invention,.sucl`ias `will :enable lothers skilled iii theiai't to whichy it appertains to make and use the saine.

This invention relates to ship construction and the primary object of .the invention is to provide a nonsinkablef ship or a ship, lthe hull of 'which is constructed so` that the ship will remain afloat in case the: portion of the hull which is submergedwin the water is punctured by a torpedo,'shellor by contact with a reef or any other object which might have a tendency to puncture the hull.

More specifically, the object of this invention is to provide a ship, the hull of which is composed of three sections which are arranged so that two of the sections will lie parallel to each other and have their inner facing sides slightly spaced while the third section extends downwardly beneath the bottom of the side or upper sections and is substantially V-shaped in cross sections, to provide a -hollow keel for the vessel.

A. further object of this invention is to provide a plurality of air retaining chambers formed along the bottoms of the two parallel sections and along the sides of the lower substantially V-shaped section to increase the bouyancy of the boat or ship and to arrange the parallel sections so as to bring all the floating-*power to bear with the surface of the water, and to have sufficient load carrying floating power to be capable of carrying the center Or lower section which is built under the two side or parallel sections, thereby further decreasing the liability ot the sinking' of the ship in case the third or center lower section is punctured.

lVith the foregoing and other objects in view this invention consists in such novel features of construction combination and arrangement of parts as will he hereinafter more fully described illustrated in the accompanying drawings and claimed.

1918; Serial No. 233,356.

like and corresponding parts throughout the several. views. and in which:

Figure l is a side elevation of `the iinproved ship having :i portion thereof broken away to show the center section in section and` a portion of one of the upper side o1l parallel sections in section, and

Figure 2 is a vertical cross section through the three sections of the ship showing them in their arranged relation.

Referring more particularly to the drawyings, l and 2 designate the upper parallel sections and 3 indicates the lower central section which is positioned between the two upper sections.

The hulls l and 2 are identical in construction, having their facing inner sides raised to form a space l through which the lower central section 3 may project to be loaded. A suitable closure 5 is provided for closing the lower portion Oi the space a and this hatch is constructed oi' a plurality oit connected chambers 6 in which are mounted air retaining pipes or reservoirs 7. The lower end of the closure 5 flares outwardly as shown at S so that in vcase the lower section 3 becomes lilled with water, the upward pressure of the water will firmly seat the closure 5 and form a fluid tight joint for the opening l so as to prevent water from passing out of the lower section 3 upwardly into the space 4.

The sections l and 2 are substantially of the usual construction or shape, being provided with partitions or bulk heads 9 which divide them into compartments or rooms and they may have any desired number of decks l0.

The bottom oi each of the sections l and 2 is composed of a plurality ot layers of connected chambers 11 in which are positioiied air retaining pipes or reservoirs to balance the sections l and 2 and cause the floating power or buoyancy ot the boat to bear upon the suri'ace of the water and also to provide sii'licient buoyancy to be capable oi' carrying or supporting the lower central section 3 in case the buoyancy of said section is destroyed by the punctiiring thereoi2 or the lling of the section with water.

The lower section 3' is substantially V- shaped in cross section, to provide .substan tially a. hollow keel tor the entire ship structure and the sides ot the lower section are vtop 18 is provided with an upwardly extending flue like extension 20 formed intermediate its ends which t in the space 4L andv thev outer edges of the top 18 may be shaped as shown at 2l to snugly lit the lower outer edges ofi the sections l and 2.

The lower middle section 3 may be provided with suitable partitions or bullr'heads 22 to divide the same into rooms or compa-rtments 23, and it is desirable to mount the engines or propelling prime movers of the ship in this portion of the ship.

ln reducing the invention to practice, certain minor l'eatures of construction combination and arrangement of parts may necessitate alterations to which the patentee is entitled provided such alterations are comprehended within the scope of what is claimed.

What is claimed is: A ship comprising a keel portion cons1sting of inner and outer plates substantially porting members to Aform second supporting members, hull sections disposed on said supporting members and in contact with said vertical walls, the second .supporting members being deliected upwardly to overlap the outer sides of saidhull sections,` a closure means operable in said space and being of a width greater than the distance between said walls and being buoyant so as to wedge between said walls under urgency of inrushing water, and said hull sections each having floatl means in thebases thereof to function to sustain the ship should water enter said space.

In testimony whereof I aix" my signature in presence of two witnesses.
